Basil L.Q. Henriques’s prayers “In Thankfulness” were first published in The Fratres Book of Prayer for the Oxford and St. George’s Synagogue Jewish Lads Club in 1916, and later reprinted in the Prayer Book of the St. George’s Settlement Synagogue (1929), “Special Prayers” section, pages 88-90. The prayer appears to be an expansion of the penultimate modim (thanksgiving) prayer near the conclusion of the Amidah. . . .
